What does an SDA tracking number look like?
The most common SDA number is a 13-character UPU S10 code: two letters, nine digits, and the suffix IT (for example, ZA123456789IT). Domestic e-commerce and business parcels may instead carry a 12-13 character mixed alphanumeric code (for example, 5P52C22026674) or a 12-digit numeric code.
