The D&B Rating is Dun & Bradstreet’s two-part business risk signal that pairs a size indicator (financial strength or employee band) with a Composite Credit Appraisal (overall credit risk from bureau-reported behavior and data sufficiency). It helps lenders and vendors segment approval tiers, credit limits, and terms.

Dun & Bradstreet assigns a two-part signal: a size indicator (e.g., 1R, 2A, 3A, 4A+) and a Composite Credit Appraisal (1–4). Together they summarize financial capacity, reporting depth, and credit behavior at a glance.
Use case: Underwriters use this fast read to determine what bucket your business enters before deeper analysis. Vendors do the same when setting net terms and limits.
Risk teams map each code to an internal policy table. Example: a “3A2” often earns higher initial limits than a “1R3” because financial capacity and reporting depth lower modeled default risk. Conversely, “–” or “DS” tells a reviewer your file is too thin or unverified to price accurately, so terms tighten.
The size indicator is largely documentary (financial statements or employee count). The composite grade reflects the quality of credit data: on-time payments, depth of trades, absence of derogatories, and data sufficiency.
Translation: More trades and cleaner public records usually improve the composite grade, but they won’t inflate your size code unless you submit stronger financials or validated headcount.
File completeness is the quiet accelerator: clean financials plus active vendor data push you into bank-ready territory faster than any single trade line.
| Tier | Signal Visibility | Typical Signals | Approval Positioning |
|---|---|---|---|
| Foundational | Minimal reporting | -- or DS; <3 trades; no financials | High risk; entry trade only; must build data |
| Build | Emerging | 1R/2R size; composite 3–4 | Moderate-to-high risk; low limits; add trades |
| Revenue-Based Ready | Robust | 2A–3A; composite 2–3; active vendors | Balanced risk; higher limits; RBF access |
| Bank-Ready | Mature | 3A–4A+; composite 1–2; clean records | Low risk; bank credit and priority terms |
Use these structured tables to decode size codes, composite grades, and example ratings:
| Code | Basis | Typical Range | Underwriting Read |
|---|---|---|---|
| -- | Insufficient data | N/A | High uncertainty; restrictive terms until data arrives |
| DS | DUNS support only | N/A | Very thin; verify identity and operations before limits |
| 1R | Employees | 1–9 employees | Micro scale; needs composite strength to offset |
| 2R | Employees | 10–49 employees | Small scale; moderate limits with clean composite |
| 2A | Financials | ~$500k–$999k net worth (indicative) | Established; eligible for mid-market vendor terms |
| 3A | Financials | ~$1M–$9.99M net worth (indicative) | Strong capacity; supports higher initial limits |
| 4A+ | Financials | $10M+ net worth (indicative) | Low modeled risk when composite is 1–2 |
| Grade | Meaning | Primary Drivers | Approval Implication |
|---|---|---|---|
| 1 | High credit appraisal | Robust trade data, timely payments, clean public records | Best terms and fastest approvals for size |
| 2 | Good credit appraisal | Solid trades, minor or no issues | Good terms; moderate documentation |
| 3 | Fair credit appraisal | Mixed or thin reporting; sporadic slow pays | Cautious limits; closer monitoring |
| 4 | Limited credit appraisal | Insufficient data, new file, or derogatories | Conservative terms; provide more documentation |
| Rating | Deconstruction | What It Signals | Next Move |
|---|---|---|---|
| 3A2 | 3A size + 2 composite | Strong capacity; good data depth | Seek higher vendor limits; consider bank credit |
| 2A3 | 2A size + 3 composite | Decent capacity; thin or mixed data | Add active trades; clear any slow pays |
| 1R4 | Employee size + limited appraisal | Very thin; conservative decisions | Submit financials; expand reporting vendors |
| DS | Support record only | Unverified for credit | Complete profile; establish 3–5 reporting trades |
| -- | Insufficient data | Unknown risk | Verify identity; upload documents and start reporting |
Submit your most recent financials to D&B, add two reporting vendors with higher limits, and monitor for data mismatches monthly. That sequence materially improves your D&B Rating trajectory and shortens underwriting cycles.
