I would like my skill to catch a mention of a 4 to 5 character code that can contain letters and numbers like AB05 or ABC12. How can I design the slots and utterances for Alexa to understand these and pass them to my skill?

laynr pointed out the best solution in my opinion. I have noticed, however, that Alexa will sometimes add a dot (.) after a spoken letter. After the string is built with multiple slots, use the following technique (shown here in Python) to remove the dots. Then the string will can be used without failure. item_number = item_number.replace('.','')

This skill https://github.com/maihde/alexa-qrz does it in the following way:
IntentSchema
1 {
2 "intents": [
3 {
4 "intent": "GetQRZ",
5 "slots": [
6 {
7 "name": "CallSignA",
8 "type": "LETTER_OR_NUMBER"
9 },
10 {
11 "name": "CallSignB",
12 "type": "LETTER_OR_NUMBER"
13 },
14 {
15 "name": "CallSignC",
16 "type": "LETTER_OR_NUMBER"
17 },
18 {
19 "name": "CallSignD",
20 "type": "LETTER_OR_NUMBER"
21 },
22 {
23 "name": "CallSignE",
24 "type": "LETTER_OR_NUMBER"
25 },
26 {
27 "name": "CallSignF",
28 "type": "LETTER_OR_NUMBER"
29 },
30 {
31 "name": "CallSignG",
32 "type": "LETTER_OR_NUMBER"
33 }
34 ]
35 },
36 {
37 "intent": "AMAZON.YesIntent"
38 },
39 {
40 "intent": "AMAZON.NoIntent"
41 },
42 {
43 "intent": "AMAZON.StopIntent"
44 },
45 {
46 "intent": "AMAZON.CancelIntent"
47 }
48 ]
49 }

You should be able to use AMAZON.LITERAL as your slot type
{
"intent": "GetCodeIntent",
"slots": [
{
"name": "code",
"type": "AMAZON.LITERAL"
}
]
}
For your utterances its a little weird as in you potentially have to define the longest your utterance may be from my experience but if the longest it will be is 5 characters you should be able to do something like
GetCodeIntent update code {one two three four five|code}
GetCodeIntent set code {one two three four five|code}
GetCodeIntent change code {one two three four five|code}
You will still refer to your intent slot using the code var
"GetCodeIntent": function (intent, session, response) {
var codeSlot = intent.slots.code;
//Do all of your amazingness with your code here
},
