3 Digit phone numbers -- how many are there where you live?

In My Humble Opinion
1

I’m pretty sure almost everybody has 411 and 911.

But I just recently learned that, around here, if you dial 211 you you get a local United Way information service that refers you to various public assistance agencies in the area.

Are there other oddball short phone numbers out there?

Calling 311 around here will get you these Charlotte-Mecklenburg government services.

In the San Francisco area, we have them all:

111 is impossible in North America
211 is human services, generally run by United Way
311 is government and non-emergency services
411 is directory service
511 is traffic info
611 is phone repair service for landlines. No idea what happens if you call from a cell
711 is hearing impaired relay service
811 is underground utility location service
911 is emergency service
011 is the international operator

The number assignments are uniform across the US. What’s not uniform is if your area has the newer services like 211 and 311 set up yet.

This is interesting. I had no idea there was any system like this. I didn’t even know about 211 until they called me to update their information about my employer – a hospital.

If I call 611 from my cellphone, I get the cellphone company’s customer service operator.

These codes were set by the North American Numbering Plan Administration, which assigns all the area codes and exchanges in North America. Here is the part of their website giving those codes.

They apply only in North America, but in fact, several other areas use the same codes.
