Here are my polygons of town blocks.
The colored towns are considered as areas where they have the same post code.
What I eventually want is to make seamless polygons where there are no gaps between polygons (please see the screenshot below)
What functions should I use to complete my mission?

@Pil Kwon, since you have the same
"post-code"
, therefore in QGIS I can suggest using a "Convex Hull":Hint: Create Convex Hulls based on a field.
