A Go port of Google's libphonenumber library for parsing, validating, and formatting international phone numbers. It tracks the Java reference implementation and embeds upstream metadata for worldwide number handling.

Use cases

• parse phone numbers from user input in Go
• validate phone numbers for a specific country region
• format phone numbers in national or international format
• get carrier or timezone metadata for a phone number
• normalize phone numbers before storing in a database
• detect invalid phone numbers in form submissions

When to choose

• you need libphonenumber functionality in a Go project
• you want a well-maintained port used in production worldwide
• you need strict parity with Google's Java libphonenumber behavior

When to avoid

• you need features not present in upstream libphonenumber
• you work in a language other than Go (use the original libphonenumber or its native ports)
• you need lightweight phone validation without full metadata overhead
