Providing a full list of phone codes for every country and region would be extensive. Here are a few resources where you can find comprehensive information:
It sounds like you're asking about NTR phone codes — but this term is not a standard mobile or telecom concept (like STD codes or IMEI numbers).
However, in certain online or gaming communities, NTR is an abbreviation sometimes used in cheat code contexts or inside jokes for mobile games (e.g., “NTR” as a parody of Konami codes). More often, “NTR” refers to a genre tag in anime/gaming (netorare), and “phone codes” might refer to USSD codes or hidden service codes on phones (*# codes). ntr phone codes full
If you meant the latter — useful hidden phone service codes (sometimes jokingly called “NTR codes” in memes) — here’s a clean, informative list for Android phones (use with caution, as some reset your device):

*57).The search phrase “NTR phone codes full” is ambiguous and does not refer to a single, standardized technical standard. Instead, it appears to be a colloquial or jargon-heavy query that can point to several distinct domains: mobile network technology, telephone number portability, or (more commonly) subcultural slang. Below is a thorough breakdown of each possibility.
In mobile telecommunications (particularly older GSM and some CDMA networks), “NTR” is not a standard acronym. However, users sometimes refer to Network Test Reports or Numeric Trouble Reports using three-letter codes. More likely, “NTR” here is a misremembering or typo for MMI (Man-Machine Interface) codes—the *# sequences used to test phones. International Access Code : This varies by country
Examples of “full” service/engineering codes that users might group under an “NTR” header include:
*#0011# – Service menu (shows signal strength, network band, etc.)*#*#4636#*#* (Android) – Phone information, battery, usage stats*#*#197328640#*#* – Service mode for Samsung phones (network lock, RF test)*#*#3646633#*#* – Engineer mode for MediaTek chipsetsWhy “NTR”? In some older Nokia or Siemens service manuals, “NTR” stood for Network Trouble Report – a diagnostic log. “Full” might refer to accessing the complete set of these diagnostic codes (often hidden or requiring a special key combination).
Reality check: There is no universal “NTR” code list. Carriers and manufacturers keep most diagnostic menus proprietary. Attempting “full” access often requires root/jailbreak or specialized software (e.g., QXDM, CDMA Workshop).
Different countries, and even different carriers within the same country, use different shortcodes for NTR. If you dial the wrong code, you may deactivate call forwarding, activate a test line, or do nothing at all. Having the full list ensures you use the correct vertical service code (VSC) for your specific provider.
