Data verification for charities and not-for-profit
Capture accurate donor, member and supporter data from the first interaction so every appeal, delivery and communication reaches the right person
Addressfinder helps charities and not-for-profit teams verify addresses, emails and phone numbers, reducing wasted resources, improving donation conversion and maintaining clean and reliable contact records.
More accurate data means less time spent on administration and more for your cause. As Australia and New Zealand experts, our verified data supports governance expectations while handling the local complexities that matter.

"Addressfinder makes sending mail to our supporters a lot more simple because we know the address is accurate." - Melinda McColl | Save the Children
The cost of inaccurate data
Bad data does not just create admin work, it takes resources away from your mission
Every incorrect address, bounced email or disconnected number means a donor misses your appeal, a tax receipt goes undelivered or a parcel is returned. The impact on postage, staff time and donor trust adds up quickly.
For charities and not-for-profit organisations, data accuracy is not just an operational issue, it's a stewardship one.

Where Addressfinder fits in your operation
1. Supporter data capture
Capture accurate contact details at the point of sign-up
Whether someone donates online, signs up for a newsletter or registers for an event, Addressfinder ensures the details they enter are complete and valid before they reach your CRM.
- Add address autocomplete to donation forms and sign-up flows to reduce manual entry errors
- Validate email addresses in real time to prevent hard bounces and protect your sender reputation
- Verify phone numbers at point of capture to keep tele-fundraising and volunteer contact lists actionable
Result: Cleaner supporter records from day one, fewer failed communications and less manual correction across your systems.

2. Multi-channel donor management
One accurate record, wherever a supporter first connected with you
Charities collect supporter data from multiple sources: website forms, face-to-face sign-ups, telemarketing agencies and direct mail responses. When each source captures data differently, your CRM can become a source of confusion rather than confidence.
- Use bulk verification to clean and standardise data from external agencies before it enters your CRM
- Utilise real-time address, email and phone verification in any online form to capture consistently formatted data at source
- Reduce duplicate records of the same supporter appearing in different formats across different sources
Result: A trustworthy database that supports better outreach, more effective fundraising and records that stand up to internal governance requirements.

3. Appeal and campaign efficiency
Know exactly who you can reach before every campaign
Undeliverable direct mail wastes precious budget, bounced emails hurt your sender reputation and disconnected phone numbers make fundraising lists unreliable.
Verifying contact data before every campaign protects your budget and gives you a true picture of your contactable audience.
- Use bulk verification to validate and standardise large donor or member lists before print runs, email or phone campaigns
- Identify and correct outdated, duplicated or incorrectly formatted records across your database
Result: More of your fundraising budget reaches potential donors rather than covering the cost of failed outreach.

4. Service and goods delivery
Ensure aid, goods and services reach the right location
For organisations moving physical goods, address accuracy at the point of dispatch directly affects delivery success rates.
- Validate delivery addresses before dispatch to reduce failed deliveries and courier return fees
- Capture accurate addresses in online stores or intake forms to prevent errors entering your fulfilment workflow
- Use address verification in internal systems to maintain consistent and standardised records across teams
Result: Higher delivery success, lower return costs and more efficient operations for your team.
