# Telephone area code (`phone_area_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.

Area code (trunk prefix and dialling code) of a telephone number written without the subscriber number, as in 0221 for Cologne or 06 for Rome in national formats; North American area codes have three digits without a leading zero (212). Directories often keep it in a column of its own.
