What does the VoP response “Not_Available” mean?

A non_available (No Answer / No Account Provider response) indicates that a definitive Verification of Payee result could not be obtained from the beneficiary bank at the time of the request. Importantly, this does not indicate a failed name match. Instead, it reflects an operational scenario where the beneficiary bank was unable to return a VoP response within the required timeframes.

Typical causes include:

• Temporary beneficiary bank unavailability or maintenance

• Timeouts or connectivity issues

• Scheme or routing interruptions

• Certain account types not being supported for VoP at that time

2. Is there a most common underlying cause?

There is no published scheme‑wide breakdown attributing Not_Available responses to specific root causes.

That said, based on operational experience across the market, temporary unavailability or degraded performance at the beneficiary bank is generally the most common contributing factor. This is most often observed during peak periods or maintenance windows. Any percentage estimates in this area should be considered indicative only.

3. Do VoP error responses vary by bank?

Yes. While the VoP Rulebook defines standard response categories, banks differ in how they implement and surface errors. As a result:

• Some banks return Not_available for a broader set of operational failure scenarios

• Others provide more specific responses where possible

• Timeout thresholds and retry behaviour also vary

• This variation is expected within the current VoP ecosystem.

4. Is Not_available more common with certain banks or IBANs?

There is no publicly available or scheme‑published data ranking banks by frequency.
Not_available However, we have observed higher rates of Not_available and HTTP 500‑type responses in some cross‑border cases, particularly involving French, Lithuanian, and Italian IBANs. This has primarily been driven by differences in interpretation of the VoP scheme rules, rather than issues with the underlying accounts.

These inconsistencies are expected to be resolved with the introduction of the VoP v1.1 Rulebook, which provides clearer alignment across participating institutions.

You can inform your customer:

We’re currently unable to verify the recipient’s bank details, so the payout cannot be completed at this time. This is usually due to a temporary issue with the bank connection and does not necessarily indicate a problem with the account details.

From your side,

Please double-check the IBAN and account holder name for accuracy and try again. If the details are correct, you may retry later or update the recipient information.

If the details appear correct and it still does not seem to be working. I would recommend asking the end customer for an alternative bank account to pay in to.
