+# BEP-87: Token Symbol Minimum Length Change
+
+## 1. Summary
+This BEP proposes to reduce the minimum length limit for token symbol on Binance Chain
+
+## 2. Abstract
+Currently, the token symbol minimum length is limited to 3. After implementing this BEP, the users are allowed to issue a token with a symbol of 2 characters.
+
+## 3. Status
+draft
+
+## 4. Motivation
+As many users have the requirements to issue a two-character token on Binance Chain, the minimum token symbol length will be changed to 2 in this BEP.
+
+## 5. Specification
+
+### Length Changes
+When the issuer sends an issue transaction for issuing BEP2/BEP8 token, the token symbol length must be between 2-8. Here is the comparison of the length check below:
+
+| **Token Type** | **Length Check(Before)** | **Length Check(After)** |
+| :------------- | :----------------------- | :---------------------- |
+| BEP2 | 3-8 | 2-8 |
+| BEP8 | 3-8 | 2-8 |
+
+After the implementation of this BEP, the token symbol length of Binance Chain would be between 2 and 8.
