616 area code — Grand Rapids, MI geographic

Data: NANPA public reports, current as of July 28, 2026.

Phone numbers beginning 616 are registered to the Grand Rapids area of Michigan (Eastern time zone). The code entered service on January 1, 1947. Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.

The code currently holds 544 working prefixes, held by 51 different carriers. Of these, 356 are pooled prefixes shared by multiple carriers. Numbers are anchored to 36 rate centers — billing localities that fix where each prefix belongs.

Practical takeaway: the 616 label narrows geography to Michigan, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

As demand grew it in turn gave rise to 231 (1999), 269 (2002).

The current NANPA exhaust forecast is 3Q 2060.
