For call centers, agencies & marketing teams
Stop wasting agent hours on inactive numbers.
Send your existing raw CRM or campaign list and find out which numbers are actually linked to live WhatsApp accounts — so your team works cleaner data instead of dialling into nothing.
WhatsApp number verification
Are bad numbers draining your campaign budget?
Working with raw, unverified contact lists means your team spends time and resources on entries that will never convert.
- Wasted agent hours. Agents spend time dialling inactive, disconnected or irrelevant numbers that go nowhere.
- Poor campaign efficiency. Raw lists carry outdated, invalid or unusable entries that inflate your outreach with zero return.
- Messy CRM data. Old lists make reporting, segmentation and campaign preparation harder and less reliable over time.
A simple done-for-you process.
No complex setup and no integration work. Send your existing list and we handle the rest.
Send your existing raw list
Share a file from your CRM, campaign tool or dialer. CSV, XLSX and TXT are all accepted.

Lawful business use only.
Marketing Wala provides list-cleaning and number-verification services for lawful business use. Clients are responsible for ensuring they have the required rights, lawful basis, permissions, consent where applicable, and opt-out screening for their intended outreach. Verification does not create permission to contact any person.
By using this service you confirm that the list is your own lawfully-obtained data and that your intended use complies with all applicable laws and platform policies. See our Privacy Policy for how submitted data is handled.
Before you send anything.
An existing raw list in CSV, XLSX or TXT format containing phone numbers from your own CRM, customer database or campaign tool. The first 10,000 submitted numbers are processed as a free sample audit.
A cleaner processed list showing which numbers were identified as active on WhatsApp. Numbers that were not found as active are flagged separately, so you can filter your list before outreach.
No. This service processes your existing list only. We do not sell scraped databases, personal profiles, names, addresses, or any data we have collected ourselves. We process only the numbers you submit from your own list.
You are solely responsible for ensuring your intended outreach follows applicable laws, platform terms, consent requirements and opt-out rules in your jurisdiction. Number verification does not create permission to contact a person.
Use the form below, or send it on WhatsApp if you would rather it never touched a web server. Either way we confirm receipt and guide you through the rest.
It depends on file size and the current queue. Send your approximate number count on WhatsApp and you will get an estimated turnaround before anything starts.
Submitted files are used only to perform the requested audit or service, and are deleted once processing is complete and results have been delivered. Ask if you want confirmation of deletion for your specific submission.
Submit your audit request.
Fill in the details and attach your list. Your file is stored on our own server, is never resold or shared, and we come back to you within 24 hours.
