Introduction

If your presentation has plenty of slides it will be easy to locate specific slides as long as you have enabled slide numbers on these slides. In PowerPoint 2010, you have to make these slide numbers visible since they don't show by default.

Following these steps will help add slide numbers to your individual slides in PowerPoint 2010.

1. Select the Insert tab of the Ribbon. Within the Text group, click the Header & Footer button, as shown in Figure 1. Alternatively you can also click the Date & Time or Slide Number buttons in the same tab of the Ribbon.
2.

2. Either way, this brings up the Header and Footer dialog box (see Figure 2). Make sure that the Slide number option is checked (highlighted in red).
3.

4. Now choose any of these options:
5. Apply to All: This will apply the slide number to all slides.
6. Apply: This will apply slide number to the current slide only.
3. You can also choose the Don't show on title slide (highlighted in red) option to disable the visibility of slide number on the title slide, typically the first slide in a presentation and all other slides based on the Title layout.

Enable Slide Numbers in the Master

If the presentation has multiple Masters and/or Slide Layouts, you can enable slide numbers in Slide Master view on a particular Slide Master so that you can control which slides show the slide number and which don't.

Follow these steps to do so:

1. Select the View tab of the Ribbon. Under the Master Views group, click the Slide Master button (see Figure 3).

2. This opens the Slide Master view, as shown in Figure 4.
   
   alt="Slide Master view" />

3. The Slides pane located on the left side of the Slide Master view has one large thumbnail that represents the Slide Master. All the smaller thumbnails represent individual Slide Layouts. Select the Master or the Layout on the left pane for which you want to enable slide numbers.
4. Select the Insert tab of the Ribbon, and click the Header & Footer button to bring up the familiar dialog box that you last saw in Figure 2 (refer earlier in this page). Select the option to enable slide numbers.
5. Choose Apply to All if you want to show slide numbers in all Masters / Layouts of the presentation, and only Apply if you want it to be visible on the current selection (Master or Layout).
6. Make sure you are on the Slide Master tab of the Ribbon, and click the Close Master View button to go back to the Normal view.

Troubleshooting Slide Numbers

Even after applying the slide numbers some times they are not visible, to make slide numbers visible follow these troubleshooting sequence:

1. Check whether the slide objects are overlapping the slide numbers in both the Normal and Slide Master views.
2. If that doesn't work, click the Slide Master button Within View tab on the Ribbon (refer to Figure 3).
3. This will take you to Slide Master view, select the Slide Master on the left pane (the larger thumbnail on the top of other smaller thumbnails). Now access the Slide Master tab of the Ribbon and click the Master Layout button, as shown in Figure 5.
   
   alt="Master Layout button" />
   Figure 5: Master Layout button
4. This opens the Master Layout dialog box, that you can see in Figure 6.
   
   alt="Master Layout" />

5. Check the Slide number checkbox, and click OK. If you have multiple Masters (more than one large thumbnail on the left pane), you'll want to summon and check the Master Layout dialog box for all the masters.
6. Go back to Normal view by clicking the Close Master View button in the Slide Master tab of the Ribbon.

Start Numbering from Zero

Do you want to start the numbering on your slides from zero rather than one? Or do you want to start it from 6 or 101? You can do it, just follow these steps:

1. Choose the Design tab from the Ribbon, and click the Page Setup button (see Figure 7).
   
   alt="Page Setup" />
   Figure 7: Page Setup
2. This opens the Page setup dialog box (see Figure 8).
   
   alt="Page Setup dialog box" />

3. Change the number in the Number slides from option at the bottom left of the dialog box (highlighted in red), as required.
4. Click OK to get back to your slides.

Start Slide Number from 31

When you put in the auto number thing so that you can see what slide number you are on, can you start that at any number? Why does it have to be zero or one, can it be 31?

Yes, it can, since we already detail how this can be done on my blog, let me lead you there, see Start Slide Number from 31.

Start on the Third, Fourth, or Another Slide

Typically you can start your slide numbering with any number, so yes, your first slide can be numbered fourth. But what if you want the opposite, maybe you want your fourth slide to be numbered first!
