Individual mobile phone companies are allocated different ranges within the 071xx, 073xx, 074xx, 075xx, 07624, 077xx, 078xx and 079xx prefixes. Changes to mobile phone numbers in the Big Number Change were mostly straight replacements, such as Vodafone customers on the 0378 block became 07778.

Mobile phones use geographic area codes (two digits): after that, all numbers assigned to mobile service have nine digits, starting with 6, 7, 8 or 9 (example: 55 15 99999–9999). 90 is not possible, because collect calls start with this number.
Mobile phone numbers moved into the 077xx, 078xx and 079xx ranges (and more recently, 075xx, 074xx, 073xx and 071xx have also been brought into use). [37] The exception to this was Manx Telecom mobile phone numbers, where the code became 07624 in order to match the 01624 used for landlines.
Country codes are defined by the International Telecommunication Union (ITU) in ITU-T standards E.123 and E.164. The prefixes enable international direct dialing (IDD). Country codes constitute the international telephone numbering plan. They are used only when dialing a telephone number in a country or world region other than the caller's.
Voice short codes enable UK mobile phone users to dial a 5-digit short code (usually beginning 6, 7 or 8 - e.g. 61500) as an alternative to a standard geographic (e.g. 01 or 02 prefix) or non-geographic (e.g. 03, 08 or 09 prefix) long number.
When dialing a mobile number, "xxx" represents the mobile operator code. All mobile operator codes begin with the number 07. "zzzzzzz" represents the main telephone number of seven digits. The country code for Sri Lanka is 94, so the format becomes "+94 XX Y ZZZZZZ" for landlines and the format becomes "+94 XX ZZZZZZZ" for mobile numbers. [4]
In the early-1990s, mobile, non-geographic and premium rate services had used nine-digit numbers with various codes such as 0402, 0645, and 0898 scattered among the similar-looking geographic area codes such as 0384, 0562 and 0949. The number of available codes for new services was quickly dwindling.
