Five vendors, five different ideas of what "pricing" means. Two won't tell you a number until you talk to sales. Two require you to spend a fixed minimum before you check a single record. One shows the cost before you pay. Here's what each actually charges, verified directly from each vendor's site.
| Vendor | Entry cost | Per-number rate | Pricing public? | SAN required? |
|---|---|---|---|---|
| DNC.com | Unpublished | Unpublished | No | Yes |
| TCPA Litigator List | $199/month | $0.002 → $0.0006 (subscription tiers) | Yes | Yes |
| Blacklist Alliance | $300 (10k block) | $0.030 → $0.0045 | Technically, but noindexed | Not stated |
| DataZapp | $125 minimum order | $0.005 → $0.002 (prepay) | Yes, prominently | Not required |
| NumberBroom | $5 minimum | $0.20 | Yes | No, for carrier validation + litigator scrub |

The honest way to read a per-number rate
Look at NumberBroom's own $0.20 next to TCPA Litigator List's $0.002 at their top subscription tier and the comparison looks lopsided — a hundred times cheaper. It only holds up at volume high enough to justify a $199-to-$4,999/month recurring commitment. For an operator scrubbing a few thousand numbers occasionally rather than continuously, the number that actually matters is total spend for the list in front of you, and the floor you have to clear to run it at all.
| Vendor | Cost for one 2,000-number list |
|---|---|
| DNC.com | Unknown until a sales call |
| TCPA Litigator List | $199 minimum (one month's subscription) |
| Blacklist Alliance | $300 minimum (smallest one-time block) |
| DataZapp | $125 minimum order |
| NumberBroom | $400 (2,000 × $0.20) |
At exactly 2,000 numbers, NumberBroom isn't the cheapest line item — but it's the only one where that $400 buys carrier validation and a litigator scrub in the same job, with no separate product, no SAN, and no commitment beyond that one upload. The other four either require a recurring subscription to reach their advertised rate, or don't publish a rate you can compare against at all.
What's actually included matters more than the rate
A per-number price is only comparable if the two vendors are checking the same thing. DataZapp's own FAQ states plainly that its Phone Scrub service "does not guarantee DNC or TCPA compliance" and "is unable to determine if specific phone numbers are disconnected" — real, disclosed limits on an honestly-priced product. Before comparing rates, confirm whether a vendor's number covers format validation only, or format plus line type plus litigator screening plus disconnect detection. Those are different products wearing the same per-number price tag.
Why some of these require a SAN and others don't
DNC.com and TCPA Litigator List both require a Subscription Account Number because their core product includes direct National DNC Registry access, which by FTC rule can only run under the seller's own credential. Blacklist Alliance, DataZapp and NumberBroom's carrier-validation-plus-litigator products don't touch registry data, so none of them require one.

Frequently asked questions
Why won't some scrubbing vendors publish a price?
Usually because the product is sold through a sales-assisted process built for larger accounts — enterprise call centers where the final number depends on integration work, seat counts, or a multi-year contract, none of which fits neatly on a pricing page. DNC.com publishes no price at all; Blacklist Alliance publishes real numbers but marks the pages noindex, nofollow so they don't surface in search. Neither is necessarily a bad vendor for the buyer they're built for — it's a signal about who that buyer is.
What's the cheapest way to scrub a small list — under 1,000 numbers?
Of the five vendors compared here, a $5 minimum on a per-number rate (NumberBroom) is the lowest entry cost for a small, one-off list. A $125 minimum order (DataZapp) or a $199 monthly subscription (TCPA Litigator List) both cost more than the list itself is likely worth checking, unless you expect to run more lists soon after.
Is the cheapest per-number rate always the best deal?
Not if you rarely hit the minimum. A vendor advertising $0.002 per number sounds far cheaper than one charging $0.20 — until you notice the $0.002 rate requires a $199/month subscription whether you use it or not. Compare the total cost for your actual volume, not the headline per-unit rate, and pay attention to whether unused capacity carries over or is forfeited.
Does a cheaper scrub mean worse data?
Not necessarily, but it's worth checking what's actually included. DataZapp's own FAQ discloses that it does not identify disconnected numbers and does not guarantee TCPA compliance — real limits on an otherwise well-priced, well-published product. Ask what a vendor's price covers before comparing it on rate alone; a per-number figure that only validates format is not the same product as one that also checks line type and litigator status.
