What Is Bulk Screening?

Bulk screening allows organisations to upload lists of names or identifiers and screen them simultaneously against sanctions and PEP datasets. It is commonly used for onboarding batches, legacy data reviews, periodic compliance checks, and large-scale portfolio screening where manual individual searches would be impractical.

Why Bulk Screening Matters

  • Increase operational efficiency by screening thousands of records simultaneously
  • Reduce manual workload associated with individual name-by-name searches
  • Standardise screening workflows across large datasets for consistent results
  • Support high-volume compliance reviews for periodic re-screening cycles

How ClearSanction Supports Bulk Screening

  • CSV upload support for names, organisations, vessels, and wallet addresses
  • Structured match results with relevance indicators and source links
  • Advanced matching to help prioritise relevant Potential Matches across large datasets
  • Exportable audit output with full match context
  • API-based automation options for programmatic bulk screening

Your Bulk Screening Compliance Workflow

  1. 1

    Prepare Your Data

    Format your list as a CSV file with names and optional identifiers (date of birth, nationality, jurisdiction, entity type). Include wallet addresses or vessel names as needed.

  2. 2

    Upload and Screen

    Upload your CSV through the ClearSanction dashboard or submit via the API. The system screens every entry against sanctions and PEP datasets simultaneously.

  3. 3

    Review Structured Results

    Results are returned in a structured format showing Potential Matches per entry, with relevance indicators to prioritise review.

  4. 4

    Investigate and Document

    Drill into individual matches to view source links, identifier details, and match rationale. Mark entries as reviewed, flag for further investigation, or dismiss as false positive.

  5. 5

    Export Compliance Reports

    Generate consolidated audit reports covering all screening results, review decisions, and timestamps — for internal records and audit review.

Bulk Screening Use Cases

Batch Customer Onboarding

Screen a portfolio of new customer accounts during a bulk onboarding event, ensuring all new relationships pass sanctions and PEP checks before activation.

Legacy Data Remediation

Run historical customer databases through sanctions and PEP screening to identify exposure in legacy portfolios that were previously unscreened or screened against outdated lists.

Periodic Portfolio Re-Screening

Re-screen the entire customer base on a quarterly or annual cycle to identify new matches since the last screening round as sanctions lists are updated.

M&A Target Portfolio Review

Screen an acquisition target's entire customer or counterparty portfolio for sanctions and PEP exposure as part of pre-acquisition due diligence.

Vendor and Supply Chain Audit

Screen all vendors, suppliers, and subcontractors in a single batch to identify any entities or beneficial owners appearing on sanctions or PEP lists.

Wallet Portfolio Screening

Upload a list of cryptocurrency wallet addresses for bulk screening against OFAC SDN sanctioned wallet listings and regulatory sources.

Bulk Screening by Industry

A bank re-screens its entire retail customer base of 50,000 accounts quarterly by uploading a CSV of all customer names and dates of birth, identifying new matches against updated sanctions lists.
A law firm conducting due diligence on a corporate acquisition screens the target company's 5,000 contract counterparties in a single batch to identify any sanctions or PEP exposure before closing.
A property management firm screens all tenants, guarantors, and beneficial owners across its portfolio of 2,000 properties in one batch upload for periodic compliance review.
