Batch and point-of-entry verification
Data Verification Services
Inaccurate customer data causes bounced mail, failed deliveries, duplicate records, and wasted outreach. Acelerar’s data verification specialists check email addresses, phone numbers, postal addresses, and business records against appropriate sources, then return clear validation statuses for your team.
Data Verification
What are data verification services?
Data verification is the process of checking existing records against appropriate sources to confirm that they are accurate, valid, and current. Cost depends on record volume, fields checked, source access, exception rate, manual review, turnaround, QA, and whether the work is a one-time batch or recurring queue. Unlike data entry, which creates records, or data cleansing, which standardizes and corrects them, verification tests whether a value can be trusted before it moves into sales, marketing, customer operations, collections, or logistics workflows.

Why Verify Your Data
Why businesses outsource data verification to Acelerar
Documented Verification Results
We apply field-appropriate checks for phone, email, postal address, and business data. Each record receives a usable status such as verified, invalid, or manual review, with the reason recorded where available.
Identify Risky Email Records Before Outreach
Hard bounces damage your sender reputation and deliverability. Our email verification catches invalid, inactive, disposable, and role-based addresses before they hit your send list.
Reduce Undeliverable Direct Mail
Address standardization and postal checks help identify incomplete, malformed, or undeliverable records before a campaign or shipment is released.
Real-Time & Batch Options
Need to verify a database of 500,000 records? Batch processing. Need to verify leads as they enter your CRM? Real-time API-based verification. We support both workflows for maximum flexibility.
Multi-Channel Verification
Email, phone, mailing address, company name, job title, and social profiles - we verify across channels so every field in your contact record is validated, not just one.
Dedicated Support From $7/Hour
Use a dedicated verification team from $7/hour for batch projects, recurring database maintenance, or review queues that need human judgment. Scope and hours are agreed before work starts.
