STC Kuwait’s two most useful codes are one digit apart — *555# for general credit, *556# for data specifically — close enough to mix up under pressure, which is exactly why a simple memory trick helps more than it sounds like it should.
Quick answer
Dial *556# for a detailed data/internet balance with package breakdown. For a general credit check instead, dial *555#.
The mnemonic worth remembering
555 is the general/credit code; 556 is data. One way to keep them straight: the extra step from 5 to 6 mirrors moving from “just money” to “something more specific” — internet. However you remember it, the key fact is that these two codes answer different questions and neither substitutes for the other.
Postpaid: the SMS fallback
If you’re on postpaid and *556# doesn’t give you what you need, send “Q” to 567 for an SMS with your internet usage details instead — a text-based alternative that’s occasionally more reliable than USSD when the network is under load.
What *556# actually shows
Beyond just a data figure, *556# breaks out each active internet package by name alongside its remaining allowance and expiry date — considerably more detail than a single “X GB left” answer, useful if you’ve stacked more than one data add-on.
