Why is my Correos de México tracking not updating or stuck?

A tracking number can appear stuck for several reasons: the item is moving between countries with no scan in between, it is waiting in a customs queue, or the destination operator has not yet scanned it. Long gaps are common on economy and international services and usually do not mean the item is lost. If there is no movement for an extended period, recheck the number, allow extra time, and then contact Correos de México or the sender to open an inquiry.
