<p>Hi Ardan,<br>
</p>
<p><br>
</p>
<p>You will face the same problem down the road when you reach 100,000 entries. Why not use the same format as the PDB -include letters in the mix? <br>

<b>Subject:</b> [3dem] EMDB accession code format</font>
<div> </div>
</div>
<div>Dear all
<div class=""><br class="">
</div>
<div class="">The current format of the EMDB accession code is EMD-#### (4 digits starting at 1001). </div>
<div class=""><br class="">
</div>
<div class="">Due to the rapid growth in EMDB we are running out of 4 digit accession codes. You will therefore see entries released in the coming weeks with accession codes in the range below 1001 but padded with leading zeros to 4 digits, e.g., EMD-0011 or
EMD-0221. Once these are exhausted we will continue with 5 or more digits.</div>
<div class=""><br class="">
</div>
<div class="">In other words EMDB accession codes will have the format:</div>
<div class="">EMD-##### where ##### is a number. If the number is less than 1000, it will be padded with leading zeros to a minimum length of 4 digits.</div>
<div class=""><br class="">
</div>
<div class="">If you have any queries about the change please feel free to contact me.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes</div>
