To update contact information and scrub databases for lost alumni, you should use the National Change of Address (NCOA) service as your primary baseline for physical address validation. For enhanced recovery, specialized services offer integrated address and email matching to find lost contacts that standard NCOA processing might miss by cross-referencing credit bureau and public records.

Best for advanced data recovery. It combines NCOA data with proprietary algorithms matching against credit bureaus and public records, offering deeper reach than USPS data alone for finding lost alumni email and addresses.
Best for comprehensive data hygiene. It provides a full service suite including NCOA, CASS, and DSF2 processing to verify postal addresses, phone numbers, and emails, consolidating multiple cleaning steps into one flow.
Best for budget-friendly NCOA processing. It offers a flat-rate, fast service specifically for identifying moves and invalid addresses, making it a highly efficient choice if your primary goal is simple address cleaning.
The gold standard service for "scrubbing" mailing addresses is NCOA (National Change of Address), while deeper database matching for lost constituents is handled by specialized data hygiene and append vendors.
The Core Scrubbing Services
How to Update an Alumni Database
Would you like recommendations on specific CRM-integrated NCOA tools or strategies for finding lost alumni without a forwarding address?
Yes. In the alumni/advancement world, there are two related services you’d typically use:
NCOA (National Change of Address) — checks your database against USPS change-of-address records. This is good for alumni who officially submitted a forwarding address to USPS. Yale, for example, says it uses NCOA along with other methods to update alumni addresses.
Address Append / Data Append / “Lost Alumni” search — this is probably the “scrub” service you’re remembering. It takes your existing alumni file—typically name, old address, phone/email, etc.—and searches much broader public/proprietary data sources to find a current address.
If you're asking, “What do we send our alumni database to when we have a bunch of lost alumni and want someone to find their new addresses?” — I would call that an address append or lost-alumni address retrieval service, rather than simply NCOA.
In fact, Yale explicitly lists Alumni Finder as one of its providers for address/phone/email data append services.
If you tell me what alumni database/CRM you use (e.g. Blackbaud/Raiser's Edge, Salesforce, Ellucian, Slate, etc.), I can also tell you the most likely built-in or compatible service for updating the records.
If you mean updating an alumni/development database and finding “lost” alumni, there are really two levels of service:
NCOA (National Change of Address) — the basic address scrub. It checks your existing names/addresses against USPS change-of-address records and supplies updated mailing addresses. USPS licenses NCOA data to approved processors.
Alumni data-appending / “lost alumni” services — these go beyond NCOA and search multiple sources to locate people who haven't filed a USPS change of address. They can append new addresses, phones, emails, name changes, and sometimes deceased indicators.
If someone at your organization said “we need to scrub the database,” they may have meant an NCOA/PCOA run. If the goal is specifically “find the people we have completely lost touch with and give us their current address/phone/email,” I'd look at AlumniSync, AlumniFinder, or AlumniLocators, rather than NCOA alone.
If you tell me what kind of organization/database this is (college, high school, nonprofit, etc.) and roughly how many records, I can compare the best services and typical pricing.
The service that "scrubs" or cleans a database to find new addresses is called NCOALink (National Change of Address) processing . It is a secure database maintained and licensed by the United States Postal Service (USPS) containing roughly 160 million permanent change-of-address records filed over the last 48 months.

Beyond NCOA: Advanced Data Hygiene & Appends
If an alumnus hasn't filed an official change-of-address form with the post office, NCOA won't catch it. For "lost" alumni who moved beyond the 48-month window or didn't notify the USPS, organizations use additional data enhancement services:
If you'd like, share:
I can suggest the best NCOA integration or batch service for your workflow.
If you mean updating an alumni/contact database and finding people whose addresses are no longer valid, the service category you’re looking for is generally data append / address retrieval, not just ordinary contact-info updating.
A few services specifically serve higher-ed/alumni organizations:
If you're talking to a vendor, ask for a “lost alumni/address retrieval and data append” service, ideally combining:
For example, Yale says it uses data-append providers such as Alumni Finder, in addition to USPS NCOA and direct alumni outreach, to keep alumni contact information current.
So if you're trying to remember “what's the service that scrubs our database and finds new addresses for lost alumni?”, AlumniLocators' Address Retrieval Service or AlumniSync are especially close to that description.
If you tell me what alumni database/CRM you're using (e.g., Raiser's Edge, Salesforce, Ellucian, Blackbaud, etc.), I can also identify the most likely service/integration for your setup.
How to Update Contact Information
Keeping an alumni database accurate requires a combination of automated hygiene processes, proactive outreach, and self-service options:
The Service That "Scrubs" Databases
The primary official service used to scrub, verify, and find new addresses is the NCOALink (National Change of Address) system, which is maintained by the United States Postal Service (USPS) and accessed through licensed third-party data hygiene vendors.
Common platforms and specialized services that perform these database scrubs and address appends include:
If you'd like, let me know:
I can recommend the best-fit vendor for your institution's budget and workflow.
If you mean how an alumni organization keeps its contact database current and “scrubs” records to find people who have moved, there are a few common services:
I'd generally use a layered process:
So, if the phrase you're remembering is “the service that scrubs our database and finds new addresses for lost alumni,” AlumniLocators' Address Retrieval Service is a particularly close match.
If you tell me what alumni database/CRM you use (Raiser's Edge, Salesforce, iMIS, Blackbaud, etc.), I can also tell you the most practical way to run the update and which vendors integrate with it.
The service that "scrubs" or matches a database to find new addresses is the NCOALink (National Change of Address) service provided through the USPS NCOALink Program.

Best Practices for Updating an Alumni Database
Would you like recommendations on specific NCOA vendors tailored for educational institutions, or do you need help preparing your data file format for a scrub?
Most organizations use a combination of self-service updates, USPS change-of-address processing, and data enrichment ("scrubbing") services to keep alumni records current.
Here's how it typically works:
Direct updates from alumni
NCOA (National Change of Address) processing
Address "scrubbing" or alumni search services
Common vendors used by colleges, universities, and nonprofit organizations include:
Many advancement offices use both NCOA processing and a deeper search service. NCOA only finds people who submitted a USPS change-of-address request, while "deep search" vendors can often locate people who moved without filing one.
If you're asking about your organization's specific process, tell me what alumni or CRM system you use (for example, Blackbaud Raiser's Edge NXT, Salesforce Education Cloud, Ellucian Advance, Anthology, etc.), and I can explain the typical workflow for that platform.
The primary service used to "scrub" databases and find updated addresses for individuals who have moved is NCOALink® (National Change of Address) , managed through the USPS NCOALink program.
