“No More *556#": MTN, Airtel, Glo, 9Mobile, NCC Announces Single Codes for Data, Airtime, 11 Other Telecom Services.
The move is directed by the NCC to make it easier for Nigerians to remember a single code for different services across all networks
All old codes for recharging, data subscription, and balance checking will no longer work
Nigeria's major telecommunications companies, including MTN, Airtel, Glo, and 9mobile, will implement a harmonised set of shortcodes for all telecommunications services from May 17, 2023.
The move, directed by the Nigerian Communications Commission (NCC), means all mobile network operators will now use the same code for services.

This will make it easier for Nigerians to memorise single codes for various services across all mobile networks.

Why the new shortcodes are important
Before the harmonisation, each telecom operator had its unique code for checking balances, recharging, borrowing credit, etc.
This required subscribers with multiple lines to memorise different codes for the respective operators.
However, with the harmonised codes, all telcos will now use the same code to carry out credit recharges, balance checks, and other telecom services.
What happened to the old codes for each network
According to a report from May 17, 2023, all old codes used to recharge, subscribe for data, and check balance, among others, will cease functioning.
The NCC has therefore asked telecom consumers to familiarise themselves with the new codes for various services.
