First I would use unlec.com to determine where it is currently allocated. The SPID/OCN tells you who has it. SPID = Service Provider ID; OCN = Operating Company Name. Then look at the LNP history, which is the history of who and when the number was assigned/re-assigned over the years. Tell both companies that you will be involving the FCC and try to reach the "porting group" who will be able to fix this. Porting problems happen all the time, even with 99% of ports (that might be an optimistic number) happening in a nearly-automatic fashion. (EDIT: I mean the porting group at each company, not the FCC).

Is there an equivalent site for the UK?

  The only thing I know of for the UK that's sort of similar (but not really), is this one: https://www.telecom-tariffs.co.uk/codelook.htm https://www.telecom-tariffs.co.uk/codelook.htm If you put in a landline or mobile telephone prefix, it can tell you which network the number was originally allocated to, but it can't tell you if the number has been ported.

  Aren't all UK numbers owned by BT?

  I don't have such a rich source as OP, but Ofcom have some information https://www.ofcom.org.uk/phones-telecoms-and-internet/information-for-industry/numbering https://www.ofcom.org.uk/phones-telecoms-and-internet/inform... https://www.ofcom.org.uk/phones-telecoms-and-internet/information-for-industry/numbering/numbering-data https://www.ofcom.org.uk/phones-telecoms-and-internet/inform...

what is a good source for this data? their terms stipulate against scraping, but I'm curious if there is an authentic "open" source for the raw data?

  Not exactly the raw data, but Twilio has a cheap and easy-to-use API for this: https://www.twilio.com/docs/lookup https://www.twilio.com/docs/lookup.

  https://developers.telnyx.com/docs/api/v2/number-lookup/Number-Lookup https://developers.telnyx.com/docs/api/v2/number-lookup/Numb... Not open but this is a decent option for bulk. I believe it runs $0.0015 per number. I don't believe it does the port history though

  The authoritative database is owned by Neustar[1] and is non-public. There are entities that subscribe to the service and fulfill those queries (such as unlec.com or whatever reseller they're getting the information via). But the Neustar revenue model is to charge per query which is why that site limits the number of queries one can perform. Every time you place a phone call in US or Canada, the originating carrier does a lookup against the Neustar-NPAC database (also called a "dip") to determine the routing destination for your call. Only after that response (called a "LRN" or location routing number) is received does call routing truly begin. 1: https://www.npac.com/canadian-number-portability/the-npac-neustar-lnp https://www.npac.com/canadian-number-portability/the-npac-ne...

Is this able to determine if the phone is connected through wifi calling? (There was a discussion yesterday where some one suggested SMS may not be sent to a phone connected to wifi only if the sender did not wish to but I could not see a mechanism that would allow that determination.)

Do we know where this site is getting its data? Given the site is down, maybe there's an option to pay for a lookup from some authoritative source.
