Telephone number information/formats

 

---

 

These data tables, built by GRC Data Intelligence, contain information about world telephone numbers and systems, designed to allow you to:

• Burst telephone numbers into their component parts (country code, international trunk code, national destination code (area code), national significant number (subscriber number))
• Check the validity of the numbers, in terms of their basic structure and length
• Identify which numbers belong to mobile (GSM) numbers, allowing, for example, SMS actions to be prepared and executed.

About five country telephone systems make changes every month.  We keep these tables updated and can provide updates as changes occur.

 

The information is provided in three files:

 

(1)  Telephone number structure file, containing over 13000 records with:

• Country codes
• International telephone country code
• International telephone trunk code
• National destination codes (area codes)

For example:

 

GB	44	0	113
GB	44	0	114
GB	44	0	115
...
US	1	1	201
US	1	1	202
US	1	1	203
...

 

(2) Telephone number length file, containing 220 records indicating the minimum and maximum allowed fixed-line (geographic) and mobile (GSM) telephone number lengths (excluding the international trunk code) by country.  For example:

 

Country	Min. fixed	Max. fixed	Min. mobile	Max. mobile
SE	7	9	9	9
CH	9	9	9	9
SY	8	9	9	9
...

 

(3) Mobile number identification file, containing over 2000 records with the first digit(s) of the area codes or subscriber numbers which indicate that a number refers to a mobile (GSM) telephone.  For example:

 

Country	Area code	Subscriber number
AS	-	733
NL	6	-
NL	06	-
VN	199	-
...
