Operator-match guide
Topping up a ported number: choose its current operator
Direct answer: ask the recipient which provider currently serves the number. Number portability lets a customer keep a number after switching, so the original prefix or an old contact label may point to the wrong operator product.
A phone number can outlive its original provider
| Clue | Reliability | Action |
|---|---|---|
| Number prefix | Can reflect the original allocation | Do not use it alone |
| Old receipt or contact label | Can predate a provider switch | Ask for a current account view |
| Recipient’s current operator app/SIM settings | Current user-facing evidence | Use the named provider and country |
New Zealand’s Commerce Commission explains that mobile number portability allows a person to switch providers while retaining the same number. The same practical risk exists wherever portability is supported: the familiar digits are not proof of the current network.
Ask one simple question
“Which operator currently bills or manages this number?” is enough. The recipient can answer from the current provider app, SIM settings or latest operator message. Do not request an account password, one-time code or a subscriber database lookup.
Keep country, current operator and value together
Open the country collection, choose the current operator and then select the local value. If the recipient cannot verify the provider, delay the purchase. A cryptocurrency invoice cannot correct an operator mismatch after fulfilment.
Common questions
Can I identify the provider from the prefix?
Not reliably for a ported number. Confirm the current operator with the recipient.
Does the recipient need to share account credentials?
No. The operator name and account type are enough for product selection.
Will a failed operator match be refunded?
No blanket recovery or refund is promised; verify before buying.
