Is 881 an area code

Answer 1

In North America, +1 881 is not in use as an area code. However, it was previously used as a "replace" code to permit paid international calls to North American toll-free 888 numbers. A foreign caller wishing to reach an 888 number could dial +1 881 and then the 7-digit number, paying the ordinary international toll charges but completing the call.

Telephone country code +881 is used for satellite phones including Iridium and Globalstar.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
