Tracking Number Formats & Auto-Detection
| Pass | Rule / Regex | Check Digit | Examples |
|---|---|---|---|
Pass 1 (matches) | UPU S10 ..PE, valid check digit | UPU S10 mod 11 | RE123456785PE |
Pass 2 (mayMatch) | none | none | none |
S10 numbers ending in PE with a valid check digit auto-detect to Serpost. Serpost also tracks mail that arrives from other posts, but those numbers belong to their origin posts, so pass ?carrier=serpost for them.

}Notes
- Language: Serpost's wording is Spanish and is kept as sent.
- Check digit: Serpost matches the start of what it is sent, so a number with a bad check digit can return a stranger's parcel. Numbers that fail the S10 check are answered
not_foundwithout a request. - Time zone: scan times are Peru time (
-05:00, no daylight saving), printed month first (03/09/2026is 9 March).
