Phone number statistics

Where reported caller IDs sit in the US numbering plan

678,203 complaints filed between June 29 and September 23, 2026 named 577,421 valid North American numbers as the caller ID. For the 488,989 with a US area code, the table gives the holder NANPA’s tables of September 27, 2026 list for the number’s thousands-block, or for its code where no block row answers. The last column is the same split of all allocated US numbers, counted in numbers.

“Nobody” is space NANPA’s tables list as assigned to no carrier on the table date: a free block in a pool, a reserved code or a code not assigned at all. A caller ID from it was not issued to anyone then. A holder is the one NANPA assigned the block to; the share of allocated US numbers counts each thousands-block as 1,000 numbers and the rest of each code as the code holder’s.

Reported caller IDs by kind of code

Toll-free numbers are 12.3% of the reported caller numbers but 49.3% of those reported 3+ times on 2+ days, the rule behind the reported_unwanted_calls signal. How the signal is scored.

Other North American codes are the Caribbean area codes, the US territories and the non-geographic services. Area codes are read from NANPA’s NPA report of September 27, 2026. 73.6% of the 633,901 complaints that answered the FTC’s question were marked “recorded message or robocall”. The FTC publishes its own totals, subjects and state breakdowns in its Do Not Call data.

FTC complaints by month

Complete months only. The reports themselves are kept for 90 days; each month is counted once it is complete and its files are in, and the counts are kept after the reports age out. The last column is the share of that month’s US-area-code caller numbers in blocks held by VoIP providers.

US numbering by holder kind

NANPA’s tables of September 27, 2026 allocate 1.88 billion US numbers: 197,177 codes of ten thousand numbers, 71.9% of them pooled, and 1,303,876 thousands-blocks inside the pooled codes, with 88,589 more blocks free in the pools. Holders on the classification list cover 54.7% of those numbers. These are shares of NANPA’s table, not of lines in use or of traffic.

Codes and blocks assigned recently

What each regulator’s table dates inside the last 7, 30 and 365 days, counted back from the table’s own date. A code or block returned since is gone from the table, so these are assignments still held. Area codes new in service or planned have a page of their own.

US codes and thousands-blocks still held, by year assigned

What NANPA’s tables of September 27, 2026 still list, by the assignment date they give. Codes and blocks returned since are gone from the table, so earlier years are undercounted, and retained blocks and codes assigned before NANPA dated them carry no date (42.9% of codes and 75.6% of thousands-blocks are dated). The holder columns count thousands-blocks; the unclassified column is part of every year, so a change between years follows which holders the list classifies as much as the market.

SMS-receiving numbers by calling code

The two open SMS-receiving lists, iP.1 Networks and Castle, synced on September 27, 2026, hold 128,362 numbers anyone can read a one-time code sent to. 19,276 (15.0%) were seen recently enough to score disposable; the rest score disposable_stale, because the sites give numbers up and carriers reassign them.

The 25,678 listed numbers with a US area code, by the block they sit in, beside the same split of all allocated US numbers. A listing last seen years ago can sit in a code returned since, which counts as nobody’s.

How these figures are made

• A number is placed by its area code in NANPA’s NPA report, then, for a US area code, by the longest prefix NANPA’s tables list for it: the thousands-block first, else the code. A free pool block, a reserved code and a code NANPA does not list at all count as not assigned.
• VoIP and wireless come from the holder’s FCC filing type and its own description, matched on the regulator’s holder name. Holders not on that list are counted as unclassified, so both the VoIP and the wireless shares are lower bounds.
• The US baseline counts numbers, not rows: each allocated thousands-block is 1,000 numbers with its own holder, and the rest of each allocated code is the code holder’s.
• A share is a share of the regulator’s table or of the reported numbers, never of traffic. Nothing here says who is calling, or who serves a number today: ported numbers keep their block.
• The FTC counts cover the 90 days of reports Spaw keeps; monthly totals are carried forward as counts once a month is complete, never as numbers.

Common questions about these statistics

Does a number in a VoIP block mean a VoIP provider made the call?

No. The figures describe the caller ID shown to the consumer, and caller ID is easily spoofed. A block records the holder NANPA assigned it to, never the network that carried a call or who serves the number today: a ported number keeps its block. The share says where the displayed numbers sit in the numbering plan, nothing more.

Is this the Do Not Call Registry?

No. The Do Not Call Registry lists consumers’ own numbers. These are complaints consumers filed with the FTC about calls they received, naming the caller ID. They say nothing about whether you may call or text a number, and they are unverified.

How is a block holder classified as a VoIP provider or a wireless carrier?

From the holder’s FCC filing type and its own description, matched on the holder name the regulator’s table gives. A holder not on that list is counted as unclassified, and the list covers 54.7% of allocated US numbers, so every VoIP and wireless share is a lower bound. No holder or carrier is named on this page.

Why is a count shown as “under 20”?

A count of reported or listed numbers under 20 is not published, and neither is its share. Nothing is cut below the area code, and nothing is counted per number or per carrier.

How far back do the FTC figures go?

Spaw keeps the FTC’s reports for 90 days, which is the window the main tables cover. Each complete month is counted once its files are in, and those counts are kept after the reports themselves age out; no number is kept.

Can I reuse these figures?

Yes. Spaw’s derived counts are CC BY 4.0 with attribution to Spaw (spaw.co); the CSV and the Markdown twin carry the same figures. The underlying data belongs to its publishers: the FTC’s files are public domain, Arcep’s are under the Licence Ouverte / Open Licence (Etalab), the SMS-receiving lists are MIT, NANPA publishes no terms of use and the CNAC’s website terms grant no licence, so their facts are shown with credit and the table date and their files are never republished.
