### About SIM search identifiers

<details>

<summary>ICCID</summary>

Integrated Circuit Card Identifier for SIM cards or profiles (when using an eUICC SIM). For more information, see [About eUICC SIM profiles](/anynet-sim/esim-and-remote-provisioning/about-euicc-sim-profiles.md).

Contains 14 and 20 numeric digits and starts with 89 or 99.

</details>

<details>

<summary>SIM ID</summary>

SIM Identifier. The unique serial number printed on the SIM provided by Eseye.

Contains between 8 and 20 numeric digits. This is valid only for eUICC SIMs.

</details>

<details>

<summary>EID</summary>

Embedded Universal Integrated Circuit Card (eUICC) Identifier. The unique global serial number that identifies an eUICC, for Remote SIM Provisioning and eUICC management purposes. For more information, see [eUICC Identifier (EID)](/anynet-sim/esim-and-remote-provisioning/euicc-overview.md#euicc-identifier-eid).

</details>

<details>

<summary>IMSI</summary>

International Mobile Subscriber Identity number. Identifies a cellular network subscriber. The network operator that provided the IMSI uses it to authenticate a SIM (and the IoT device containing the SIM) on the network.

Contains between 15 and 16 numeric digits.

</details>

<details>

<summary>MSISDN</summary>

The Mobile Station International Subscriber Directory Number (MSISDN) is a unique identifier for a mobile phone number in telecommunications. It includes the country code, mobile network code and subscriber number, allowing for routing of calls and messages to the correct device. The MSISDN contains between 8 and 18 numeric digits and can include the '+' country code identifier, for example: +441234567890.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.eseye.com/infinity/sim-estate-management/how-to-view-and-manage-sim-details.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
