Check one US or Canadian phone number, toll free or local, by digits or by its spelling (877-393-7552 or 877-EYES-LLC). Use it when someone asks whether a number is available, what it costs, or what it is today. Returns its status (available, backorder, rent to own, with another vendor, in use, or for a local number the phone company first given its block, when, and the company that has it today, with each company's page on NewLocalNumbers.com), its price when it has one, and links to its history and to finish on VanityNumbers.com. When the number spells a word, it also names the word and lists numbers like it that can be ordered.
DiscoveredFind toll free numbers for a type of business, like PLUMBING, DENTIST or LAWYER: the best ones available now (from 1800AVAILABLE.com) and recently disconnected ones that can be requested, up to 10 of each. Use it when someone wants to browse numbers for their kind of business rather than one word. Returns each number's price, and links to its page and to the category's page to see more.
DiscoveredSee a toll free number's history from Resporgs.com: which RespOrgs (the companies that manage toll free numbers) have held it and when, and its status in each span, from the toll free registry's records. Use it when someone asks who had a toll free number before, or how long it has been with its current company. Returns the current holder, each earlier span, newest first, and a link to the number's page on Resporgs.com.
DiscoveredPass along a person's request for a toll free number held by another vanity number vendor, the kind check_number and the searches show as with another vendor, with no list price. Use it when the person asks to request that number and gives their name and email. Bill Quimby at VanityNumbers.com reviews each request by hand to confirm it's available and what it would cost, and answers by email, usually within a day; it costs nothing to ask. Returns whether it was sent and what happens next. It can't buy or reserve the number.
DiscoveredFind a new phone number for a business that spells a word, like 1-800-PLUMBER: toll free (800, 888, 877, 866, 855, 844, 833) or local in a state. Use it when someone wants a memorable or vanity number, an 800 or toll free number, or a number that spells their business name or what they do; give it that word (PLUMBER, BAKERY). Returns the word in all seven toll free area codes with each one's status and price, a recommended pick, close versions available for $49, local numbers in a state when one is given, the word's business category pages, and links to finish on VanityNumbers.com. It doesn't look up an existing business's phone number.
DiscoveredSet up a notification about a toll free or local phone number for a person who wants an email when it changes: a number they want that someone has today, or a local number whose block no phone company has been given yet. Use it when the person asks to be told about a number and gives their email address. VanityNumbers.com emails them a link to confirm, and nothing starts until they click it. Then they get what we have on it now. A toll free number is followed with the same 7 digits in all 7 toll free area codes; a local number with every version of it in its state, a check each month of whether it's still in use, and, if no phone company has its block yet, when our data shows one was given it. After that they get an email on the 15th when it or a related number has changed, and every three months to say the notification is still on. Returns whether the confirm email went out. It can't buy or reserve a number.
