What a first day cover is
A first day cover is an envelope bearing a postage stamp canceled on its first day of issue. Look for a clear postmark with a date and usually a town name; this proves the mailing date. First day covers are relevant to philately because the combination of stamp, postmark, and envelope documents the stamp's launch and affects how collectors identify and value the item. First day cover abbreviated FDC appears on many reference pages and auction listings — expect to see that exact phrase in catalogs.
Check the envelope design (the cachet)
Examine the envelope art: the cachet is the printed envelope design that accompanies the stamp. Cachet: printed envelope design can be simple or elaborate; it is often printed on the left side of the envelope and may include artwork, text about the issue, or the issuing authority. A printed cachet that matches the stamp topic supports the identification of the piece as a first day cover.
Inspect the stamp and postmark closely
Look at the stamp for denomination, country, and issue name. Check the postmark for an exact date; a first-day postmark will match the stamp's issue date. Inspect perforations, gum (on unused stamps), and any tying marks where the postmark overlaps both stamp and envelope. Condition affects collect interest and perceived value. Use a loupe or magnifier to identify small details and any printer's inscriptions that can confirm the issue.
Use a scanner and reference sources
If you need a record, create a high-resolution scan of the envelope and stamp using a flatbed scanner. A good scan shows the postmark date, cachet, and stamp design clearly. Compare the image to stamp catalogs, online databases, and philately forums to identify the issue and learn more about issuance details. Keep scanned files organized so an identifier tool or a catalog search returns consistent results.
When to use a digital identifier
After you have checked postmark date, cachet design, and stamp details, use a digital identifier if you still need confirmation. A good identifier accepts a scan and returns likely matches from catalogs, helping you confirm the issue and typical market descriptions.

Common questions
- How do I know the postmark is a first-day cancellation?
- The postmark will show the exact issue date; it may also be labeled as a 'First Day of Issue' in some postal services. Confirm the date matches the stamp's published issue date in a catalog.
- Does every first day cover have a cachet?
- No. Many first day covers include a cachet, but some are plain envelopes with only the stamp and postmark. When present, the cachet supports identification because it is often linked to the stamp topic.
- Can a scanned image prove authenticity?
- A high-quality scan can document visible features like postmark date, cachet, and stamp details, and it helps when comparing to references, but physical inspection is still useful for condition and gum verification.
