Generate carrier-format tracking number samples for testing — format samples only, not real shipments.
FORMAT SAMPLES ONLY: generated numbers match carrier patterns for testing. They are not real shipments, are not trackable, and must never be presented as genuine tracking numbers.
How to use this tool
UPS, FedEx (12 or 15 digits) or USPS (20 or 22 digits).
Each click makes a fresh random sample in that pattern.
Checkout, label-printing and scanning demos that need a plausible-looking number.
Carriers will not recognise these numbers — that is the point.
Formula & worked example
UPS gives an 18-character sample starting 1Z followed by 16 letters/digits; FedEx 12-digit gives 12 random digits.
Limitations — read this before you rely on it
Format samples only, for testing. They are not real shipments, are not trackable, carry no check-digit guarantee for the carrier's internal validation, and must never be given to a customer as a genuine tracking number.
Frequently asked questions
No. These are format samples, not real shipments — carriers will not recognise them.
UPS: 1Z plus 16 alphanumeric characters. FedEx: 12 or 15 digits. USPS: 20 or 22 digits starting 94.
For testing checkout, label-printing and scanning flows that need a plausible-looking number without a real parcel.
Never — that would be a genuine tracking number claim for a shipment that does not exist.
No. Only the outward pattern is reproduced; internal carrier check-digit rules are not computed.
