566 Area Code
Personal communications services
The 566 area code is reserved for special services (Non-Geographic Services). Numbers in it are used for personal communications services in the 5YY non-geographic pool.
How 566 is used
Numbers in 566 are used for personal communications services such as one-number follow-me forwarding. The called party (the subscriber) pays for the call while the calling party is billed at standard long-distance rates. All 5YY codes share the same purpose and pool of central-office assignments.

History
Creation: Area code 566 was placed into service on April 17, 2012 as the fourth 5YY non-geographic NPA, relieving 544. It was one of the codes (alongside 577, 588 and 522) originally designated by the Industry Numbering Committee for future personal communications service. The same month, NANPA issued Planning Letter 703 reserving more than 20 additional 5YY codes for later use.
Relieved: Area code 566 was activated to relieve 544.
Mnemonics: Prior to 1995, the middle digit of area codes was restricted to 0 or 1 — codes created before then cannot form mnemonics.
