+### Overriding Default Serializer Ids
+
+> [!WARNING]
+> Changing the identification does not change the serialization binding, it only change the identification used by the serializer when it serialize a message. In fact, depending on the code, this might actually break the serializer as it might expect a specific identifier. You have been warned.
+
+Generally, overriding a default serializer identification is not recommended. The more recommended way is to change the serialization binding as was done when we [replace the default serializer with Hyperion](xref:serialization#how-to-setup-hyperion-as-the-default-serializer).
+
+In the rare case where you do need to override them, you can do it in one of two ways:
+
+* Overriding the `Identifier` property in your custom serializer class that inherits from the `Akka.Serialization.Serializer` abstract class. The `Identifier` property will override any HOCON settings; in fact, you will get a warning in your log when you do that, reminding you that you actually did that.
+* Overriding the identifier inside your HOCON settings. To do this, you have to both change the original default serializer id and declare your own serializer using the original default serializer id.
+
+```c#
+ serialization-identifiers {
+  "Akka.Serialization.NewtonSoftJsonSerializer, Akka" : 1000001
+  "MyAssembly.MyDefaultSerializer, SomeAssembly" : 1
+}
+ ```
+
+this would in effect results this final HOCON settings:
+
+```c#
+serialization-identifiers : {
+    "Akka.Serialization.ByteArraySerializer, Akka" : 4
+    "Akka.Serialization.NewtonSoftJsonSerializer, Akka" : 1000001
+    "Akka.Remote.Serialization.ProtobufSerializer, Akka.Remote" : 2
+    "Akka.Remote.Serialization.DaemonMsgCreateSerializer, Akka.Remote" : 3
+    "Akka.Remote.Serialization.MessageContainerSerializer, Akka.Remote" : 6
+    "Akka.Remote.Serialization.MiscMessageSerializer, Akka.Remote" : 16

+    "MyAssembly.MyDefaultSerializer, SomeAssembly" : 1
