Platform

Every step of 1583 compliance, in one verified pipeline.

Photo-ID Verification

Capture and authenticate government-issued IDs with real-time liveness and tamper checks.

Proof-of-Address Verification

Automated OCR against utility bills, bank statements, and leases — matched to the applicant.

1583 E-Signature

Pre-filled Form 1583 with legally binding signatures captured under ESIGN and UETA.

USPS Submission

Native file transfer to USPS. Receive a signed acknowledgment in your dashboard in minutes.

ID Expiration Alerts

Automated expiration alerts give users time to update their IDs before they expire, reducing compliance risks and minimizing manual follow-up.

How it works

Five steps, from checkout to ongoing compliance.

Purchase

Customer buys a virtual address plan from your storefront or checkout.

Upload

They upload ID and proof-of-address via a branded Colleckt flow.

Sign

Pre-filled 1583 is e-signed in-session with audit trail captured.

Submitted

Colleckt files with USPS and returns acknowledgment to your dashboard.

Stay Compliant

When IDs approach expiration, Colleckt automatically sends alerts to re-verify before they lapse.

Security & compliance

Built for teams that carry regulatory weight.

Encryption at rest and in transit

TLS 1.3 for every request. Keys rotated quarterly.

Role-based access control

Granular roles for reviewers, admins, and API clients with SSO + SCIM.

Data residency

US-only storage by default, with optional tenant-level residency controls.

Audit logs

Immutable event stream for every verification action, exportable to your SIEM.

PII minimization

Documents are redacted post-review and purged to your retention window.

USPS-native filing

Direct submission channel to USPS — no intermediaries, no email workarounds.

Developers

A REST API your engineers will actually enjoy.

Three endpoints, idempotent by default, webhooks for every state change. Kick off a verification with a single request and redirect the customer to a hosted flow — or embed it in your own UI.
