O2 Web Top-Up not recognising a valid O2 PAYG number

[pgn]

My monthly web top-up for younger son's PAYG phone failed at the first hurdle earlier, complaining that the entered mobile number (tried with leading 0 or leading +44, no difference!) is not an O2 PAYG Number, see screenshot below.

Web top-up for his sister's phone worked fine.

I usually copy-paste the appropriate number from my phone contacts each time I top either phone up.

This PAYG number has never, since getting it direct from O2 some 3 or so years ago, been with another provider.

I eventually got the phone topped-up via 4444, using the credit card I usually use for the purpose of top-ups, see the PS below for observations on the 4444 service experience.

 - What has changed to make my attempted web top-up of the number fail all of a sudden?

PS. The 4444 top-up line works fine, but is (a) tedious, (b) error-prone as the number has to be manually entered, and (c) asks for details in a different order from the web top-up page - first the number to be topped-up, then credit card details, address validation and postcode validation next, then, at the very end, the required top-up amount.

The other PAYG number in the house whistled straight through the Web Top-Up process, weird!

The Top up by phone number is fine, however Top up by voucher still has the wrong number
