General Questions

What is the Financial Identifier Translator?

The Financial Identifier Translator is a tool that allows you to convert between different types of financial identifiers, including ISIN, WKN, CUSIP, SEDOL, and VALOR. These identifiers are used to uniquely identify financial instruments such as stocks, bonds, and other securities across different markets and systems.

Is this service free to use?

Yes, the Financial Identifier Translator is completely free to use. There are no hidden fees or subscription requirements.

How accurate are the conversions?

Our conversion algorithms follow the standard rules for each identifier type and include validation checks. However, please note that not all conversions are possible due to the nature of the identifiers. For example, an ISIN can only be converted to a WKN if it's a German security (starts with 'DE').

While we strive for accuracy, we recommend verifying critical conversions with official sources. Please see our disclaimer for more information.

About Financial Identifiers

What is an ISIN?

ISIN stands for International Securities Identification Number. It's a 12-character alphanumeric code that uniquely identifies a specific security internationally. The structure is:

  • First 2 characters: Country code (e.g., US for United States, DE for Germany)
  • Next 9 characters: National Security Identifier (can include the local identifier like WKN)
  • Last character: Check digit calculated using the Luhn algorithm

Example: US0378331005 (Apple Inc.)

What is a WKN?

WKN stands for Wertpapierkennnummer, which is German for "securities identification number." It's a 6-character alphanumeric code used primarily in Germany to identify securities.

Example: 865985 (Apple Inc.)

What is a CUSIP?

CUSIP stands for Committee on Uniform Securities Identification Procedures. It's a 9-character alphanumeric code used primarily in the United States and Canada to identify securities.

  • First 6 characters: Issuer code
  • Next 2 characters: Issue-specific code
  • Last character: Check digit

Example: 037833100 (Apple Inc.)

What is a SEDOL?

SEDOL stands for Stock Exchange Daily Official List. It's a 7-character alphanumeric code used primarily in the United Kingdom and Ireland to identify securities.

  • First 6 characters: Security identifier
  • Last character: Check digit

Example: 2046251 (Apple Inc.)

What is a VALOR?

VALOR is a numeric identifier used primarily in Switzerland to identify securities. Unlike other identifiers, VALOR numbers can vary in length but are typically 6-9 digits.

Example: 908440 (Apple Inc.)

Using the Tool

How do I use the Financial Identifier Translator?

Using the tool is simple:

  1. Select the type of identifier you have from the "Identifier Type" dropdown
  2. Enter the identifier value in the input field
  3. Select the type of identifier you want to convert to from the "Convert To" dropdown
  4. Click the "Convert" button
  5. The result will appear in the "Result" field

You can also copy the result to your clipboard by clicking the copy button next to the result field.

Why can't I convert my identifier?

There are several reasons why a conversion might fail:

  • The input identifier is invalid or in the wrong format
  • The conversion between the selected types is not possible (e.g., converting a non-German ISIN to WKN)
  • The security might not have an identifier of the requested type

If you're sure your input is correct, try converting to ISIN first, then from ISIN to your desired type.

What does "Conversion successful using verified database entry" mean?

This message appears when the conversion was performed using our reference database of verified ISIN-WKN pairs for common securities.

While the standard conversion algorithms work for most cases, there are exceptions where the conversions can be complex or non-standard. For these cases, we maintain a database of verified identifier pairs for common securities to ensure accurate conversions.

When you see this message, it means the conversion result is highly reliable as it comes directly from our verified database rather than algorithmic conversion.

How do you ensure conversion accuracy?

We ensure conversion accuracy through multiple approaches:

  • Reference Database: We maintain a database of verified identifier pairs for common securities from trusted financial sources
  • Validation Algorithms: We use standard validation algorithms for each identifier type to ensure input validity
  • Pattern Recognition: Our system recognizes common pattern variations in identifiers to handle edge cases
  • Regular Updates: We regularly update our algorithms and database to improve accuracy

For critical financial operations, we still recommend verifying results with official financial sources.

Is my data saved or shared?

Your conversion history is saved locally in your browser's storage for your convenience. This data never leaves your device and is not shared with our servers or any third parties.
