How It Works

Three steps to a
verified lead list.

No contracts. No monthly fees. Upload, scrub, download.

Upload your CSV

Drag and drop a file with up to 5,000 phone numbers. Client-side validation catches format issues instantly.

We scrub the list

Every number runs through two filters: carrier-level line type detection (removes landlines and VoIPs) and our TCPA litigator database (flags known serial litigators). Both checks happen in parallel.

Download clean CSV

FAQ

Frequently asked questions

Everything you need to know about phone list scrubbing, TCPA compliance, and how NumberBroom works.

What is a TCPA litigator?
A TCPA litigator is a person who has filed or is known to file lawsuits under the Telephone Consumer Protection Act (TCPA). These serial litigators intentionally keep their numbers active on marketing lists to receive unsolicited calls or texts, then sue businesses for $500 to $1,500 per violation. NumberBroom checks every number against a regularly updated TCPA litigator database and flags known litigators before you ever dial.
How do I clean a phone list for cold calling?
To clean a phone list for cold calling, you need to: (1) validate each number at the carrier level to confirm it is active and identify the line type (mobile, landline, or VoIP), (2) remove landlines and VoIP numbers that cannot receive texts or are unlikely to convert, (3) run every remaining number through a TCPA litigator database to flag known serial litigators, and (4) normalize numbers to E.164 format for dialer compatibility. NumberBroom does all four steps in a single CSV upload with results in minutes.
How much does it cost to scrub a phone list?
NumberBroom charges $0.044 per row with no monthly subscription or minimum commitment. A 5,000-number list costs $220. This includes both carrier-level phone validation (line type, carrier name) and TCPA litigator checking in a single job. Competitors like DNC.com charge $300+/month, ActiveProspect charges per-scrub plus a subscription fee, and TCPA Litigator List charges $130+/month for litigator checks alone.
Do I need to scrub my list for TCPA compliance?
Yes. Under the TCPA, businesses that make unsolicited calls or texts to consumers can face fines of $500 to $1,500 per violation. Serial TCPA litigators actively seek out these calls to file lawsuits. Scrubbing your list against a TCPA litigator database removes known litigators before you dial, significantly reducing your legal exposure. NumberBroom bundles TCPA litigator checking with phone validation so you get both protections in one step.
What is E.164 phone number format?
E.164 is the international phone number format standard defined by the ITU. It includes a plus sign (+), the country code (e.g., 1 for US/Canada), and the subscriber number with no spaces, dashes, or parentheses. Example: +15551234567. Most dialers, CRMs, and SMS platforms require E.164 format. NumberBroom automatically normalizes all uploaded numbers to E.164 during processing.
What is phone number validation?
Phone number validation is the process of checking whether a phone number is active, identifying its carrier, and determining the line type (mobile, landline, or VoIP). This is done by querying carrier-level databases in real time. Validation helps businesses avoid wasting time and money dialing disconnected numbers, landlines, or VoIP numbers that will not convert.
How is NumberBroom different from DNC.com?
NumberBroom is a pay-per-job phone scrubbing tool built for SMB outbound sales teams, while DNC.com is an enterprise-focused subscription service. NumberBroom charges $0.044/row with no monthly fee (DNC.com starts at $300+/month). NumberBroom bundles phone validation and TCPA litigator checks in one job (DNC.com sells them as separate products). NumberBroom offers a simple CSV upload UI (DNC.com is API-first). NumberBroom includes a free 5-row preview with no credit card required.
How is NumberBroom different from BriteVerify?
NumberBroom and BriteVerify both validate phone numbers, but NumberBroom also includes TCPA litigator checking, which BriteVerify does not offer. NumberBroom charges $0.044/row for the combined service. BriteVerify charges $0.008/verify for phone validation only, with no litigator protection. BriteVerify is primarily an email verification tool, while NumberBroom is purpose-built for outbound phone list scrubbing with carrier-level validation, line type detection, and legal compliance.
What is the best tool to clean a phone list before cold calling?
The best phone list cleaning tools run two checks: carrier-level phone validation (to confirm the number is a real, active mobile number) and a TCPA litigator check (to flag known serial lawsuit filers). NumberBroom bundles both checks in a single CSV upload job at $0.044 per row with no subscription. You upload your list, see the exact cost, pay via Stripe, and download your clean file in minutes. Competitors like DNC.com require monthly subscriptions starting at $300+, while BriteVerify offers phone validation but no litigator protection.
How do I remove invalid phone numbers from my CSV?
Upload your CSV to a phone validation service that supports bulk processing. The tool will normalize all numbers to E.164 format (+1XXXXXXXXXX), identify each number as mobile, landline, or VoIP, and flag numbers that cannot be parsed or are disconnected. NumberBroom does this automatically using carrier-level lookups. Invalid numbers, landlines, and VoIP numbers are filtered out, and you download a clean CSV containing only verified mobile numbers with carrier name and line type appended.
