# UN/ECE Recommendation 21 package type code (`unece_rec21_package_code`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Two-character code of a type of package from UN/ECE Recommendation 21, used in customs declarations, UN/EDIFACT and UBL documents, for example BX for box or CT for carton. Codes use uppercase letters and digits in any combination (BX, 1A, 43). Many other two-character codes have the same shape, such as country codes, so the field name is the evidence.
