Phone Append Service
Every lead in your CRM should have a number you can dial.
Send us each contact's First Name, Last Name, Address, City and Zip. We return current, verified mobile and landline numbers, labelled by line type and screened against Do Not Call lists, usually within a day.
First 1,000 records free · No credit card · Your file is encrypted and deleted after the test
A name without a number is a lead nobody can work.
You paid to acquire those leads. When half of them arrive with only a name and a mailing address, reps skip them, campaigns stall, and the list quietly loses value week after week.
Appending a current, verified phone number turns that record into one your team can call and text the same day. Nothing new to buy: just more out of the list you already own.
Selling to businesses
Reach the decision-maker, not the front desk, with direct lines and verified mobiles for the people who sign.
Selling to consumers
Know which contacts carry a mobile, so you can plan calls and permission-based texts around real reachability.
Running a dialer floor
Fewer dead dials means more talk time per shift, lower cost per conversation and a team that stays motivated.
Clean numbers, not just more numbers
A big file of stale matches costs you more than it saves. Every number we return passes the same checks before it reaches your dialer.
Labelled by line type
Each number is tagged mobile or landline, so you can split call and text campaigns and apply the right dialing rules to each.
Screened before you dial
We flag numbers on Do Not Call lists and numbers that have changed owners, so your reps don't reach people who never opted in.
Only live numbers
Disconnected and dormant numbers are dropped, and every match carries a confidence score so you can dial the strongest first.
Refreshed every week
Our phone data is updated weekly, so the number you get reflects who owns it now, not who owned it a month or more ago.
From spreadsheet to dial-ready in four steps
To return current, accurate numbers we match on the full name and address. Every record needs these five fields:
- First Name
- Last Name
- Address
- City
- Zip

Frequently asked questions
It means attaching a current phone number to a contact record that doesn't have one. You supply what you know about each person, and we fill in the missing number from our weekly-refreshed data.
How it works
- You send: First Name, Last Name, Address, City and Zip for each contact. All five are required.
- We search: each record is matched on the full name and address against consumer and business phone data updated every week.
- You receive: the same list, now with mobile or landline numbers added where a match was found, with line type, DNC status and a confidence score.
Where it's used
- CRM clean-up: refreshing records that have gone stale or were never complete.
- Outbound: opening call and text campaigns to contacts you could previously only mail.
- Compliance: screening lists against Do Not Call registries as part of the same run.
First Name, Last Name, Address, City and Zip for every record. Matching on the full name and address is how we return the right person's current number instead of a guess.
Every week. Most appending services refresh monthly, if that, so their numbers can be weeks out of date by the time you dial.
[Add guarantee terms here, e.g. what happens if a matched number is disconnected or belongs to someone else.]
Match rates run up to 99% on complete name and address files, and every match carries a confidence score so you can dial the strongest first.
Only if you ask for it. We focus on phone append; email is added to your file only when you include it in your order.
Appending a phone number is legal, but how you contact people is regulated. Every number comes with line type and Do Not Call status so your team can follow TCPA rules. [Have your compliance team confirm this answer.]
From $0.02 per matched record, based on 100K records a week. Records we can't match are free, and your first 1,000 records are free to test.
Batch files typically come back within about 24 hours. The live API returns a number the moment a lead comes in.
Your file is transferred encrypted, used only to run your append, and deleted after the test. We never sell or share it.

Frequently Asked Questions
Everything you need to know about phone appending — turnaround times, match accuracy, database sizes, and TCPA compliance.
Data appending is the process of adding missing information to your existing customer database by matching your records against comprehensive database and filling in gaps like phone number, email addresses, and demographic details to create complete customer profiles.
Mortgage phone append is the process of adding verified mobile numbers to mortgage lead records — including purchase leads, refi inquiries, FHA/VA applications, and pre-qual forms. Because aggregator leads (LendingTree, Bankrate) often have incomplete contact info, mortgage phone append ensures your LOs can actually reach borrowers while they're still actively shopping.
Most of our data append projects are completed within 24 hours, with smaller databases (under 50,000 records) often processed the same day, while larger or complex datasets may take 3-5 business days. We offer 24-hour rush service specifically for time-sensitive purchase leads or time-critical debt relief campaigns when speed-to-contact is essential.
Our data append process delivers 99% accuracy through verified sources and multiple quality checks, while maintaining enterprise-level security. All phone numbers come from TCPA-compliant, and we maintain full documentation for RESPA compliance requirements along with FTC-TSR compliance.
Every number we append is run through real-time DNC registry scrubbing, Reassigned Number Database (RND) verification, wireless carrier identification, and a litigator scrub. RESPA documentation is included for mortgage use cases. TCPA compliance is included in the base $0.02/match price — not an add-on.
Premium Phone Append can add or update contact information (phone numbers, emails, addresses), demographic data (age, income, marital status), business details (company, job title), lifestyle information (interests, purchasing habits), and also clean existing data by removing duplicates and correcting outdated information.
Industries that rely on customer contact see the biggest benefits from phone appending services, including debt solutions and debt settlement companies, mortgage and lending companies.
We specialize in bulk processing and our typical projects start at 10,000+ records, we regularly process databases exceeding 10 million records for enterprise clients.
