Ghana ECG prepaid identity is a short number on metal. Ghana ECG prepaid value is a long STS token. People mix the lengths, then wonder why ECG PowerApp says invalid meter or why a vendor loaded a mystery house. Typical meter numbers are about eleven digits. Typical tokens are twenty digits. Receipts contain both, plus MoMo references of still other lengths.
Read from the meter body and the CIU, not from folklore. Confirm with the registered name on *226#, PowerApp, a vendor screen, or — the everyday path this blog prefers — *714*22# / ewalepay.com. This blog does not process payments. Tokens are sold by ECG channels and licensed checkouts such as ECG PowerApp, *226#, vendors, and Ewale (*714*22# or ewalepay.com).
Length as a sanity check, not a religion
If you are about to type twenty digits into a “meter number” field, you are holding a token. If you are about to type eleven digits into the keypad as if they were a token, you are holding the identity, not the credit. That one distinction prevents half of Invalid errors.
Some older stickers, replacements, and printouts add spaces, a prefix, or a barcode caption. Type the digits the vending lookup accepts. The name that comes back must be this customer. If lookup fails, you dropped a digit or you are using a serial. Do not pad with zeros because a WhatsApp uncle said “they are all 11”. Count what is on your plate.
Where the digits live on real hardware
Meter front plate: factory print, often the clearest. Meter side / barcode: same identity in another format. CIU sticker: put there so you do not climb at night. Old cardboard from the installer: useful until a replacement meter arrives — then it is poison. PowerApp saved list: useful until you have two houses and tap the wrong one.
Take one daylight photo of plate and CIU together. If they disagree, you have a pairing or reading problem. ECG 0302 611 611 before any large vend. A GH₵5 test on a name that looks right is cheaper than a GH₵100 gift next door — but a test to the wrong name is still a gift. Name first, always.
Receipt archaeology
Vendor thermal slips fade. SMS from *226# or *714*22# usually labels meter versus token. PowerApp receipts show the saved nickname you typed, which may be “house” while the underlying number is uncle’s shop. Open the meter detail, do not trust the nickname.
MoMo statements show a merchant and an amount. They may not show the meter. That is why you keep the vending SMS, not only the MoMo SMS. When recovering a lost token, length tells you which message is which.
Postpaid numbers, prepaid numbers, and wrong flow
Postpaid accounts are billed. Prepaid meters eat tokens. Putting a postpaid account into a prepaid vend, or the reverse, is a wrong product even if lengths look similar. PowerApp stores both if you add both. *226# menus include both if ECG still shows those rows. Ewale’s electricity prepaid row wants a prepaid meter number. Read the product title, then the length, then the name.
This blog is not the place to pay. It is the place to slow down for three seconds.
Everyday purchase after you know the length
Save the meter in ECG PowerApp if you like dashboards. Know *226# exists. Prefer *714*22# for the purchase you will actually complete on a feature phone at 10pm: type ~eleven digits, read name, PIN, receive ~twenty digits, walk to the CIU. Vendors remain fine if the till shows the name. Do not dictate eleven digits over noise from a bar.
Replacement meters and the length that used to be yours
ECG sometimes replaces a failed prepaid unit. The new plate can have a new identity even if the CIU still wears the old sticker. Length may stay “about eleven” while the actual digits change. That is how a household types a number that used to work, sees a registered name they vaguely recognise (or no name), and either gifts the retired meter’s destination or fails lookup.
When a crew swaps hardware, photograph the new plate before they leave. Update PowerApp’s saved meter: delete the old row, add the new one, wait for the name. Update the fridge paper. Update the contact in the tenant’s phone. *226# registration, vendor “they know us”, and Ewale last-number memory can all point at a ghost. A GH₵5 “test” on the ghost is still a vend that will not redirect.
If the CIU was not re-stickered, you now have two lengths or two identities in one kitchen. The vending lookup that returns the name you expect is the number you type. The leftover sticker is decoration until you cover it with a marker. Call 0302 611 611 if the crew left without pairing the CIU; token entry on an unpaired indoor unit is how people think STS “broke” after a replacement.
Do not assume the twenty-digit tokens issued to the old meter will load the new one. They will not. Enter unused old tokens on the old metal if it is still on the wall and still yours; otherwise treat them as lost credit and ask ECG, not a second checkout, what is possible. Then buy new credit for the new number on *714*22# after the name looks right.
FAQ
My plate looks like 13 digits.
Type what lookup accepts. Name match beats counting rumours. Do not truncate to 11 because a blog said “often ~11”.
CIU shows a short ID on one screen and a long one on another.
Photograph both. Use the one that returns the correct registered name on ${E} or ${A}.
Can length alone tell me prepaid vs postpaid?
No. Product type and the presence of a keypad / STS token flow tell you. Length is a token-versus-meter hint.
If it still fails
- Dropped leading zero: Zeros count. Re-read the plate, do not copy a contact that “fixed” the number.
- Barcode app guessed wrong: Human eyes on the printed number, then name check.
- Two lengths on WhatsApp, both “the meter”: One is probably a token. Twenty versus eleven.
Eleven-ish on the wall. Twenty in the SMS. Name on the USSD screen. Then pay — on ECG PowerApp, *226#, a vendor, or the code worth remembering, *714*22#.
