Serpost Tracking

Serpost tracking lets you follow a parcel handled by Servicios Postales del Perú S.A., the state-owned national postal operator of Peru. Paste your tracking number into the tracker at the top of this page to see the latest scan, where the item is in the network, and its delivery or customs status. Serpost carries most letters, registered mail, EMS express items, and the cross-border e-commerce parcels that enter Peru from abroad, so a single Serpost number can cover a domestic letter in Lima or an inbound order from China.

Serpost is Peru's sole member of the EMS Cooperative, which gives it exclusive rights to the Express Mail Service brand inside the country (EMS, 2024).

Serpost Tracking Number Format

A Serpost international tracking number is a 13-character code built on the Universal Postal Union (UPU) S10 standard: two letters, nine digits, then the letters "PE" for Peru. A typical example is EE123456789PE, where "EE" marks an EMS express item and "PE" is Peru's ISO country code as the originating post. The first two letters identify the service class, the nine digits are the unique item number (the eighth digit is a check digit), and the suffix names the country of origin.

Serpost uses several names for the same code: article number, registered-item number, EMS number, or simply tracking number. Whatever the seller or counter clerk calls it, an item that can be followed scan by scan carries an S10 code of this shape.

Keep the seller's order ID separate from the postal tracking number. The order ID (for example a long alphanumeric reference from a marketplace checkout) identifies your purchase to the store, but it is not a postal tracking number and will not return scans in a Serpost or multi-carrier tracker. Only the S10 code ending in "PE" (or the origin country's two-letter code for an inbound item) follows the package through the postal network.

Where to Find Serpost Tracking Number

The Serpost tracking number appears wherever the item was accepted into the postal network. For an item you post in Peru it is printed on the counter receipt; for an inbound order it comes from the seller once the parcel ships by post. Common places to find it:

• The postal receipt handed to you at a Serpost counter when you lodge an item.
• The shipping confirmation email or SMS the seller sends once the order dispatches.
• The order or shipment page inside a marketplace account, where the postal number appears after the item ships.
• The address label or customs declaration attached to the parcel itself.

For an inbound order from a store such as AliExpress, the merchant usually supplies the S10 number once the item leaves the origin country, and that same number becomes scannable on Serpost only after the parcel reaches the Lima exchange office. If all you have is a long checkout reference, that is the seller's order ID, not a postal number, and it will not return scans until the merchant issues the real S10 code.

Serpost Tracking Number Example

Serpost numbers follow the UPU S10 service-prefix convention. The table below lists the prefixes you are most likely to see, what each one indicates, and a sample pattern. Prefixes follow the international S10 scheme, so the first letter signals the broad service class; the exact second letter is assigned in sequence and does not, on its own, guarantee a specific speed.

If your number does not match any of these shapes, it is most likely the seller's internal order reference rather than a postal code. Wait for the merchant to issue an S10 number, or ask them to confirm the parcel shipped by post.

Serpost Tracking Status Guide

Serpost tracking events describe each stage of an item's journey through the Peruvian postal network and, for international mail, the handoff between postal operators and customs. The table below maps the common statuses to what is actually happening to your parcel.

Why Serpost Tracking Is Not Updating or Not Working

Serpost tracking can pause for several days during an international handoff, and a gap between scans rarely means the parcel is lost. Most stalls trace back to one of the reasons below.

Wrong number. Confirm you are following the postal S10 code, not the seller's order ID. A long alphanumeric checkout reference is not a postal number and returns no scans; only an S10 code (two letters, nine digits, and a country code such as PE) is tracked through the network.

Awaiting the first Serpost scan. For an inbound order the first Peruvian event appears only once the parcel physically reaches the Lima office of exchange. Until then the tracking may sit at the origin post's last scan, which looks stalled but is normal for cross-border mail handed off by partners such as China Post.

In flight between countries. The longest silences happen while an item is in the air or moving between postal operators, when no new event is recorded for days at a time. This is expected on the international leg and resolves once the destination post scans the item.

Held in customs. Inbound parcels often stop updating after "arrived at inward office of exchange" because they are waiting on Importa Fácil processing. SUNAT can hold a postal shipment for up to two months before it is returned to origin (SUNAT, 2024), and items over the duty-free threshold need your action, so watch for a Serpost arrival notice.

Genuinely delayed. If an item has shown no scan for more than a week beyond its expected window, check the most recent location and contact Serpost with the tracking number to open an inquiry. Ask the seller first for inbound orders, since the merchant can confirm whether and when the item actually shipped.

Serpost Services and Delivery Times Compared

Serpost runs domestic mail, registered mail, EMS express, parcel post, and the Exporta Fácil and Importa Fácil customs programs, each with its own speed and tracking level. The table below compares the main services and realistic transit windows; all times are estimates, not guarantees, and customs review can extend any international figure.

Serpost Delivery and Transit Times Across Peru

Serpost delivers across Peru's three natural zones: the Pacific coastal desert, the Andean highlands, and the Amazon basin, through a network of 158 offices (Serpost, 2024). Delivery inside metropolitan Lima and Callao, where the headquarters in Los Olivos and the main international processing center sit, is the fastest part of the network, often completing within one to three days of a domestic posting.

Transit to regional capitals such as Arequipa, Trujillo, Chiclayo, Cusco, and Piura typically runs three to six business days, while remote Amazon-basin and high-Andes destinations like Iquitos, Puerto Maldonado, or villages reached by river and mountain road can take longer because of the terrain. International items add the airport handoff at Jorge Chávez International Airport in Callao, which handles all inbound and outbound international postal traffic for the country.

Peruvian transit times are broadly comparable to neighboring South American posts. If you also receive parcels from across the region, the same S10 logic applies to Ecuador Post, Bolivia Post, and Correos Chile, each of which hands off to and from Serpost on cross-border mail.

Receiving Inbound Parcels Through Serpost and Importa Fácil

Importa Fácil is the SUNAT program that lets Serpost clear inbound postal shipments worth up to US $2,000 without a licensed customs broker. How a parcel is handled depends entirely on its declared value, and the duty-free threshold is the key number to know.

Shipments valued at up to US $200 are classified by SUNAT as direct distribution: no customs procedure and no import tax apply, and the item is released to Serpost for immediate delivery (SUNAT, 2024). For shipments valued above US $200 and up to US $2,000, SUNAT generates an Importa Fácil Declaration (DIF), and any duties must be paid at an authorized bank before Serpost delivers the parcel.

"If the merchandise contained in a shipment has a value of up to US $200.00, you do not have to perform any customs procedure, since SUNAT places it at the disposal of Serpost S.A. for delivery to the recipient." (SUNAT, Importa Fácil, 2024.)

When customs needs your action, Serpost sends a physical arrival notice and you can follow the case using the DPO or arrival-notice number Serpost provides. A postal shipment can be held for a maximum of two months, after which it may be returned to origin or turned over to SUNAT, so respond promptly to any notice.

Which Countries Does Serpost Deliver To?

Serpost international tracking reaches virtually every country that exchanges mail through the Universal Postal Union, having been part of the UPU network since Peru joined on April 1, 1879. Domestically it reaches all 24 departments plus the Callao constitutional province, covering coastal cities, Andean highland towns, and Amazon-basin districts from a 158-office network.

For international mail, Serpost hands parcels to partner postal operators and airlines at the Lima exchange office, and the destination country's own post completes the final delivery. As Peru's EMS Cooperative member, Serpost offers tracked express service to the large EMS network worldwide. Common destinations and origins include:

• Domestic: Lima, Callao, Arequipa, Trujillo, Chiclayo, Cusco, Piura, Iquitos, Huancayo, Tacna
• North America: United States, Canada, Mexico
• South America: Chile, Ecuador, Bolivia, Colombia, Argentina, Brazil
• Europe: Spain, Italy, Germany, France, United Kingdom
• Asia Pacific: China, Japan, South Korea, Australia

Within the region, Serpost connects to neighboring operators such as Colombia Post for mail moving up the Pacific coast, with the same UPU framework governing how each item is scanned and exchanged.

Serpost Cross-Border Customs and International Handoff

Every international Serpost item passes through the Lima inward or outward office of exchange, the single gateway where Peruvian postal mail crosses the border. Outbound parcels are scanned as "arrived at outward office of exchange" before they depart on a flight from Jorge Chávez International Airport; inbound parcels are scanned at the inward office before SUNAT assesses them.

For exports, Serpost administers Exporta Fácil, a government-backed program that gives small and micro enterprises access to international trade without a licensed customs broker, using a simplified electronic declaration tied to the EMS or parcel service. For imports, the Importa Fácil rules above govern duty and delivery. Duties and taxes on dutiable items are the recipient's responsibility, and high-value or restricted goods may be diverted to a standard customs regime rather than the simplified postal one.

What Is Serpost?

Servicios Postales del Perú S.A., trading as Serpost, is the state-owned postal service and courier of Peru, owned by the Ministry of Transport and Communications. It was created on November 5, 1991 through Supreme Decree #685 and formally began operating on November 22, 1994, succeeding the Dirección General de Correos y Telégrafos, which had held the postal monopoly since 1916 (Serpost, 2024).

Peru's postal roots run far deeper: an organized colonial postal system dates to 1791, making the country's postal infrastructure among the oldest in the Americas. Today Serpost employs roughly 563 postal workers and 1,744 other staff across 158 offices, handling correspondence, money orders, and the national and international parcel market while fulfilling Peru's universal postal service obligation. Its head office is in the Los Olivos district of Lima, with the principal mail processing center in Callao next to the international airport.

Serpost has become a central channel for cross-border e-commerce into Peru. The operator reported that demand for products bought on foreign websites grew about 30% in the first half of 2024, reflecting how much of its inbound volume now comes from online shopping rather than traditional letter mail.

Serpost Marketplace Collaborations

Serpost is one of the main postal channels delivering cross-border e-commerce orders to Peruvian shoppers, especially lower-value parcels that travel through the international postal stream rather than private express couriers. Peru is a heavy cross-border shopping market: 83% of online buyers already purchase from global websites, mostly from China, and price is the leading reason (Ipsos Peru, 2024).

Chinese marketplaces dominate inbound flow. Orders from AliExpress, Temu, and Shein frequently arrive as postal packets that Serpost clears through Importa Fácil and delivers, and AliExpress alone is used by around 47% of local cross-border buyers. Some platforms route through private logistics partners instead: Temu, for example, works with Aeropost for customs clearance and last-mile delivery in Peru, so not every marketplace order is a Serpost item.

Global and regional platforms round out the mix. Parcels from Amazon, Mercado Libre, and the Peruvian retailer Falabella reach buyers through a combination of postal and courier delivery depending on the seller and shipping method chosen at checkout. Whenever the seller ships by post and gives you an S10 number ending in "PE" or an origin country code, you can follow the parcel with Serpost tracking on this page right through to delivery.
